Ok, so I am looking at replacing the 7.5 16 tyres on our ambulance 110 as they are original from 1985 and starting to show signs of age - only done 32000 miles mind!

Was thinking of getting a tyre wheel combo from Tyres Direct with Colway AT tyres for the improved road holding (the ones currently on are 'Super Agar' and look like Tractor treads!)

So to my question..... what is the worst conditions people have been in and not got stuck with BFG AT or Colway AT?

Most of the events we cover are Horse cross country or motocross but they can get muddy some times!
